TK-61 led and pcb question

I’ve been doing a ton of reading on modding this light I plan on doing the resistor mod this week and wanted to de-dome it. This will be my first de-dome and was planning on doing the gasoline dome removal method. From the looks of it I drop the led with the pcb into the gas for a few hours and it pops right off. What I’m worried about is screwing it up mainly the pcb because I can’t seem to find that board online. I suppose I’d like to have a backup pcb and a few extra led’s I’ve founf a few led’s at mouser but no pcb. Any help would be greatly appreciated. Ithink I found exactly what I need: this shouldbe compatable with my current driver since its the same led right?

Thank you,

The gas won't affect the MCPCB. Don't worry about it unless you're planning to do something else to destroy it.
